Sec. 468.02  Specialized definitions.

    In addition to the definitions set forth in 40 CFR part 401 and the 
chemical analysis methods in 40 CFR part 136, the following definitions 
apply to this part:
    (a) The term ``alkaline cleaning bath'' shall mean a bath consisting 
of an alkaline cleaning solution through which a workpiece is processed.
    (b) The term ``alkaline cleaning rinse'' shall mean a rinse 
following an alkaline cleaning bath through which a workpiece is 
processed. A rinse consisting of a series of rinse tanks is considered 
as a single rinse.

    (c) The term ``ancillary operation'' shall mean any operation 
associated with a primary forming operation. These ancillary operations 
include surface and heat treatment, hydrotesting, sawing, and surface 
coating.
    (d) The term ``annealing with oil'' shall mean the use of oil to 
quench a workpiece as it passes from an annealing furnace.
    (e) The term ``annealing with water'' shall mean the use of a water 
spray or bath, of which water is the major constituent, to quench a 
workpiece as it passes from an annealing furnace.
    (f) The term ``cold rolling'' shall mean the process of rolling a 
workpiece below the recrystallization temperature of the copper or 
copper alloy.
    (g) The term ``drawing'' shall mean pulling the workpiece through a 
die or succession of dies to reduce the diameter or alter its shape.
    (h) The term ``extrusion'' shall mean the application of pressure to 
a copper workpiece, forcing the copper to flow through a die orifice.
    (i) The term ``extrusion heat treatment'' shall mean the spray 
application of water to a workpiece immediately following extrusions for 
the purpose of heat treatment.
    (j) The term ``heat treatment'' shall mean the application or 
removal of heat to a workpiece to change the physical properties of the 
metal.
    (k) The term ``pickling bath'' shall mean any chemical bath (other 
than alkaline cleaning) through which a workpiece is processed.
    (l) The term ``pickling fume scrubber'' shall mean the process of 
using an air pollution control device to remove particulates and fumes 
from air above a pickling bath by entraining the pollutants in water.
    (m) The term ``pickling rinse'' shall mean a rinse, other than an 
alkaline cleaning rinse, through which a workpiece is processed. A rinse 
consisting of a series of rinse tanks is considered as a single rinse.
    (n) The term ``off-kilogram (off-pound)'' shall mean the mass of 
copper or copper alloy removed from a forming or ancillary operation at 
the end of a process cycle for transfer to a different machine or 
process.
    (o) The term ``rolling'' shall mean the reduction in the thickness 
or diameter of a workpiece by passing it between rollers.
    (p) The term ``solution heat treatment'' shall mean the process 
introducing a workpiece into a quench bath for the purpose of heat 
treatment following rolling, drawing or extrusion.
    (q) The term ``spent lubricant'' shall mean water or an oil-water 
mixture which is used in forming operations to reduce friction, heat and 
wear and ultimately discharged.
    (r) The term ``Total Toxic Organics (TTO)'' shall mean the sum of 
the masses or concentrations of each of the following toxic organic 
compounds which is found at a concentration greater than 0.010 mg/l.

Benzene
1,1,1-Trichloroethane chloroform
2,6-Dinitrotoluene ethylbenzene methylene chloride napthalene
N-nitrosodiphenylamine anthracene phenanthrene toluene trichloroethylene

    (s) The term ``alkaline cleaning rinse for forged parts'' shall mean 
a rinse following an alkaline cleaning bath through which a forged part 
is processed. A rinse consisting of a series of rinse tanks is 
considered as a single rinse.
    (t) The term ``pickling rinse for forged parts'' shall mean a rinse, 
other than an alkaline cleaning rinse, through which forged parts are 
processed. A rinse consisting of a series of rinse tanks is considered 
as a single rinse.
    (u) The term ``tumbling or burnishing'' shall mean the process of 
polishing, deburring, removing sharp corners, and generally smoothing 
parts for both cosmetic and functional purposes, as well as the process 
of washing the finished parts and cleaning the abrasion media.
    (v) The term ``surface coating'' shall mean the process of coating a 
copper workpiece as well as the associated surface finishing and 
flattening.
    (w) The term ``miscellaneous waste stream'' shall mean the following 
additional waste streams related to forming copper: hydrotesting, 
sawing, surface milling, and maintenance.
    (x) The term ``precious metals'' shall mean gold, platinum, 
palladium and

[[Page 659]]

silver and their alloys. Any alloy containing 30 or greater percent by 
weight of precious metals is considered a precious metal.
    (y) The term ``beryllium copper alloy'' shall mean any copper alloy 
that is alloyed to contain 0.10 percent or greater beryllium.
